I am trying to export a grid with different row heights.

I have AutoSizeRows = true.

On the apps screen the grid looks great. :)

But when I export it I get an error:

rowHeight should be greater or equal than 0 and less or equal than 600.

 spreadExporter.CellFormatting += spreadExporter_CellFormatting;

I have a spreadExporter_CellFormatting function and had:

if (e.GridCellInfo.RowInfo.Height > 600)
            {
                e.GridCellInfo.RowInfo.Height = 600;
            };

But it didnt stop the error happening.

Question, how do I check for the Row height value and set it before/during the export?

Thanks

Deasun.

Hello Deasun,

Thank you for reporting this.

After testing the described scenario I was able to receive the same exception when there is a row with RowHeight > 600. This is why I have logged it in our Feedback portal by creating a public thread on your behalf. You can track its progress, subscribe for status changes, and add your comments on the following link: feedback item.

I have updated your Telerik Points.

To workaround the issue you can create a custom SpreadExportRenderer and override its SetWorksheetRowHeight method:

class MySpreadExportRenderer : SpreadExportRenderer
{
    public override void SetWorksheetRowHeight(int rowIndex, int rowHeight, bool isCustom)
    {
        if (rowHeight > SpreadsheetDefaultValues.MaxRowHeight)
        {
            rowHeight = (int)SpreadsheetDefaultValues.MaxRowHeight;
        }
        base.SetWorksheetRowHeight(rowIndex, rowHeight, isCustom);
    }
}

I hope this helps. Do not hesitate to contact me if you have other questions.
